User Guide
Enter keyword(s) and/or category/ies. Selecting categories for a query makes a search more specific. For example, you can retrieve sentences that contain the word HSN and a
Oryza sativa
gene name by typing the keyword 'SPW1' and choosing the category 'gene (Oryza sativa)'. A category hit occurs when a particular word or phrase in the sentence is defined as a member of a particular category. Categories will be concatenated by a Boolean 'and' operation to other categories and keyword(s) if present. To search for terms in categories, click on the Categories/Ontology link above.
Keywords
Separate multiple,

keywords by white spaces (Boolean 'and').
Separate multiple,

keywords by a comma with no white spaces (Boolean 'or').
Enter phrases in double quotes, and put a '-' sign in front of words which are to be excluded.

Narrow your search results with filter:
Put a '+' sign in front of words which have to be included, a '-' sign in front of words which have to be excluded. Enter the field of the word,
viz
author, title, year, journal, abstract, type or sentence in square brackets. Enter phrases in double quotes.
For example, to find all the papers in the search result that have
Jack
as author, but not
John
, enter +Jack-John[author]. To exclude all papers that have the phrase
double mutant
in title, enter -"double mutant"[title]. You can combine several filters and enter something like +Jack-John[author] -"double mutant"[title] +1994[year] -review[type].

Title:

Abstract:
Using a two-element iAc/Ds transposon-tagging system , we identified a rice ( Oryza sativa L cv Nipponbare ) recessive mutant , anther indehiscence1 (
aid1
) , showing partial to complete spikelet sterility . Spikelets of the
aid1
mutant could be classified into three types based on the viability of pollen grains and the extent of anther dehiscence . Type 1 spikelets ( approximately 25% ) were sterile due to a failure in accumulation of starch in pollen grains . Type 2 spikelets ( approximately 55% ) had viable pollen grains , but anthers failed to dehisce and/or synchronize with anthesis due to failure in septum degradation and stomium breakage , resulting in sterility . Type 3 spikelets ( approximately 20% ) had normal fertility . In addition ,
aid1
mutant plants had fewer tillers and flowered 10 to 15 d later than the wild type . The Ds insertion responsible for the
aid1
mutation was mapped within the coding region of the
AID1
gene on chromosome 6 , which is predicted to encode a novel protein of 426 amino acids with a single MYB domain . The MYB domain of
AID1
is closely related to that of the telomere-binding proteins of human , mouse , and Arabidopsis , and of single MYB domain transcriptional regulators in plants such as PcMYB1 and ZmIBP1 .
AID1
was expressed in both the leaves and panicles of wild-type plants , but not in mutant plants .
